There was no significant difference in the incidence of OASIS between waterbirths and the general obstetric population (2.3% vs. 2.0%). Having a waterbirth was associated with a lower probability for an intact perineum (odds ratio [OR]\u2009=\u20090.83; confidence interval [95% CI]: 0.73\u20130.94) when compared with the general obstetric population (44.7% vs. 51.3%). Nulliparous women with a waterbirth when compared with multiparous women had an eightfold higher likelihood for the occurrence of OASIS (OR\u2009=\u20098.28; 95% CI: 2.64\u201325.86). The risk for a higher degree of OASIS was associated with increased maternal age in the total sample (OR\u2009=\u20091.08; 95% CI: 1.06\u20131.11) and with a lower body mass index (BMI) at booking in multiparous women (OR\u2009=\u20090.96; 95% CI: 0.92\u20130.99). The risk for any type of perineal trauma was associated with increased maternal age in the total sample (OR\u2009=\u20091.10; 95% CI: 1.07\u20131.13) and with a lower BMI at booking in multiparous women (OR\u2009=\u20090.95; 95% CI: 0.91\u20130.99).<br \/>\nConclusions: We found that giving birth in the water reduced the chance of having an intact perineum. We have also shown that nulliparity, increased maternal age in all women, and a lower BMI at booking in multiparous were associated with OASIS and lower rates of intact perineum in waterbirths.<\/p>\n<p><a href=\"https:\/\/www.liebertpub.com\/doi\/10.1089\/jwh.2019.8244\">Link to full-text<\/a> [no password required]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Type of publication: Journal article Author(s): *Dimitrios Papoutsis, Angeliki Antonakou, *Adam Gornall, and Chara Tzavara Citation: Journal of Women's Health; May 2021; vol. 30 (no. 5); p. 681-688 Abstract: Background: To determine the incidence of and predictors for obstetric anal<span class=\"ellipsis\">&hellip;<\/span><\/p>\n<div class=\"read-more\"><a href=\"https:\/\/www.library.sath.nhs.uk\/research\/2020\/09\/29\/the-incidence-of-and-predictors-for-severe-perineal-trauma-and-intact-perineum-in-women-having-a-waterbirth-in-england-a-hospital-based-study-2020\/\">Read more <span class=\"screen-reader-text\">The Incidence of and Predictors for Severe Perineal Trauma and Intact Perineum in Women Having a Waterbirth in England: A Hospital-Based Study (2021)<\/span><span class=\"meta-nav\"> &#8250;<\/span><\/a><\/div>\n<p><!-- end of .read-more --><\/p>\n","protected":false},"author":12,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"content-type":"","footnotes":""},"categories":[200],"tags":[979,1003,441,986,966],"class_list":["post-6216","post","type-post","status-publish","format-standard","hentry","category-staff-publication","tag-979","tag-bronze-open-access","tag-children","tag-obstetrics-and-gynaecology","tag-waterbirth"],"_links":{"self":[{"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/posts\/6216","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/users\/12"}],"replies":[{"embeddable":true,"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/comments?post=6216"}],"version-history":[{"count":4,"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/posts\/6216\/revisions"}],"predecessor-version":[{"id":6629,"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/posts\/6216\/revisions\/6629"}],"wp:attachment":[{"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/media?parent=6216"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/categories?post=6216"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.library.sath.nhs.uk\/research\/wp-json\/wp\/v2\/tags?post=6216"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
